The Impact of Family Income on Child Achievement: Evidence from the Earned Income Tax Credit: Reply
回应了Dahl和Lochner（2012）研究中发现的数据编码错误，证明修正该错误后，关于家庭收入通过劳动所得税抵免影响儿童学业成就的核心结论依然成立。
Dahl and Lochner (2012) provides some of the first causal evidence of the effects of family income on child achievement using changes in the Earned Income Tax Credit. Unfortunately, a coding error in the creation of total family income affects the first stage estimates and inflates the instrumental variable (IV) estimates. Importantly, it does not affect the reduced-form estimates or alter statistical significance of the IV estimates. This response shows that correcting this error does not alter the core findings or main message of the paper.
